| 中文摘要: |
| 基于α衰变的两势方法理论模型,采用考虑了同位旋效应的唯象cosh型α-子核核势和考虑了壳效应及质子—中子相互作用的α预形成因子解析式系统地计算了最近新合成的短寿命核素223Np及其α衰变链上核素α的衰变半衰期.计算结果表明,采用考虑了壳效应及质子—中子相互作用的α预形成因子的α衰变半衰期的理论计算结果能更好地符合实验数据.这项工作可以作为将来实验和理论研究α衰变及核结构的参考. |
| 英文摘要: |
| Based on the α decay theoretical model of two-potential approach,the α decay half-lives of new synthesized short-lived nucleus 223Np and the nuclei on its α decay chain are systematically calculated by adopting the phenomenological α-daughter nucleus potential considering the isosipin effect,and the α preformation probabilities analysis formula considering the shell effect and proton-neutron interaction.The calculations indicate that the calculations of α decay half-lives with α preformation probabilities considering the shell effect and proton-neutron interaction can well reproduce the experimental data. This work will be as a reference for experimental and theoretical study of α decay and nuclear structure in the future. |
